Support #7134
Use of PTRC.Op to issue trip to PIU
0%
Description
During IOP 2024, an IED do not have the DO PTRC.Tr in its data model to issue a trip to the PIU. It uses PTRC.Op.
https://redmine.ucaiug.org/issues/6960
See IEC 61850-7-4 Ed2.1 Subclause 6.11.1:
« The protection functions provide (if applicable) the data object Op (Operate) without direction information. The data object Op is conditioned by LN PTRC resulting in the data object Tr ("real" trip), that in between every protection LN and the circuit breaker node XCBR shall be a LN PTRC . »
Does the standard allow an IED that does not perform conditioning not to implement PTRC.Tr?
The IEC 61850 standard should limit the number of ways to issue a trip between different IEDs. As pDO could be used in PIU to specify the expected input, if only PTRC.Op exists, it would not match.
Proposal descriptions
During the UCA IOP triage meeting, it was suggested that TF 7-5/7-500 be consulted.

A clarification is needed in the standard to state that PTRC.Tr must exist if the PTRC instance trips the breaker. 7-500 will cover the issue.
